The Dyson Pure Cool Link automatically purifies to remove 99.95% of allergens and pollutants as small as 0.1 microns. It monitors, reacts and purifies - then reports to your Dyson Link app, so you can remotely control your environment. You can easily monitor your indoor air quality and see live air quality metrics. If it's hot, you might need personal cooling and purified air throughout the room. But there's no need for two machines - your purifier's more powerful settings will generate smooth, long range airflow to cool you.
